Polar Sphere v1
Post date: Jun 15, 2013 11:46:43 AM
This is a parameterised custom MCEdit filter that plots a function in polar co-ordinates within your selection box.
Version 2 allows you to specify the angle bounds (min/max) to be rendered - you can now draw segments of the sphere.
Use this to:
make custom foliage and plants
create swirly spheres
generate swishing circular paths
make spherical meshes
create propeller-like things
make interesting spheres with some structure to them.
The options are:
Path Length: How many iterations of the function to run. If your shape is truncated, increase this number and re-run.
Horizontal Period: This is a multiplier for the number of revolutions of angle in the horizontal plane each function iteration
Vertical Period: This is the multiplier for the number of revolutions of angle in in the vertical plan each function iteration.
Radius Period: The line length is derived from the smallest dimension of the selection box, but this parameter can cause it to change in a sinusoidal way with each iteration.
Radius Percent Gap: If greater than 0, this will leave space in the middle of the object and only draw a path near the edge.
Terminating Block: If True, this only draws the last block in the line each iteration (i.e. the edge block).
Compound Angles: If True then the next angle is calculated using the sum of previous angles. If False, it uses a fixed step size each iteration.
Some examples with parameters:
